Abstract

<P>PROBLEM TO BE SOLVED: To provide a method by which a caregiver can easily run a drive wheel idle and wipe off dirt while sitting in a wheelchair because it is not easy to wipe off the dirt when the drive wheel of the wheelchair gets dirty and it is not rare to use the same wheelchair indoors and outdoors. <P>SOLUTION: The stand can float the drive wheel (main wheel) and run it idle while sitting in the wheelchair. While the frame of the wheelchair is floated utilizing the action of a lever, since the height of the frame is not fixed and it is needed to match an action point with an individual height, the mechanism is incorporated. Also, by firmly attaching the action point-fulcrum to the wheelchair-floor and making it hard to slip, the stable lever operation is obtained, and the caregiver can safely and easily perform the operation. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  The present invention relates to a wheelchair stand that can float and idle a drive wheel (main wheel) of a wheelchair.

  Conventionally, as a measure for preventing the indoor floor from being polluted and scratched when riding indoors with a wheelchair traveling outdoors, a tool for covering a dirty wheel with a wheelchair wheel cover sewn in accordance with the wheelchair wheel shape has been used. (For example, see Non-Patent Document 1)

In addition, a wheelchair is mounted on a device having a roller / brush that rotates with power and a cleaning liquid, and a device for removing the wheelchair wheel from the wheel has been developed. (For example, see Patent Document 1)
Patent Publication No. 2004-17733 “Seikatsu Support Catalog VOL.9”, Yamashita Corporation, 2007, p. 101

  However, the wheel cover requires a lot of time and effort to wear it, and has the drawbacks of significantly reducing the basic performance of the wheelchair, such as running, and the devices with rollers and brushes are generally large, and it is not popular for wheelchair users. Not progressing.

  Under such circumstances, wheelchair wheels can be decontaminated by transferring multiple wheelchairs outdoors or indoors, or when the passengers get off from the outside when they enter the indoors (or leave the passengers on) and lift the wheelchairs manually. Methods such as cleaning the wheels and traveling back and forth repeatedly on a mat placed on the floor are taken.

  As a result, the caregiver's time and physical burden is large, and problems such as low back pain are not only apparent, but it may also be a factor that limits social participation opportunities such as going out of wheelchair users.

  The present invention is intended to solve the problems of conventional wheelchair users and caregivers, and easily floats the driving wheel (main wheel) of the wheelchair with a simple structure to enable idling. The purpose is to make it easier to carry out decontamination of wheelchair wheels.

  In addition, since the present invention allows the driving wheel (main wheel) of the wheelchair to easily float and idle, it contributes to wheelchair wheel replacement, wheelchair repair and adjustment.

  In order to solve the above problems, the first invention uses a frame that constitutes a wheelchair, uses a floor surface as a fulcrum, a wheelchair frame action point, and a wheelchair vehicle body rear frame by the action of a lever provided with a power point at an appropriate position. Is a multi-purpose stand for wheelchairs having a structure that allows the drive wheels (main wheels) to float at a height sufficient to idle.

  In addition, since the height of the wheelchair frame varies depending on the model, the second invention has a structure in which the positional relationship between the fulcrum and the action point (height of the action point from the floor) can be adjusted as appropriate.

  Furthermore, as a third invention, after attaching the lever having the above structure to the wheelchair frame, until the assistant shifts to a posture where the assistant can easily apply force, the appropriate position is maintained even if both hands are released from the structure, and Also, while applying force to the power point, it is possible to easily operate by realizing a shape that generates appropriate friction between the structure, the frame, and the floor surface.

  According to these inventions, the wheel drive wheel (main wheel) of the wheelchair can be easily floated and idling, and it is easy to carry out decontamination of the wheelchair wheel, as well as wheelchair wheel replacement, wheelchair repair and adjustment. Convenience can be provided.

  Hereinafter, embodiments of the present invention will be described with reference to FIGS.

  In FIG. 1 and FIG. 2, a base 1 serving as a fulcrum of the lever is connected to a lifting rod 3 that lifts a wheelchair frame 15 via a height adjustment base 2. The lifting rod 3 has a circular cross section, and is passed through a hole in the height adjusting base 2 that is opened slightly larger than its diameter, and is not fixed but rotates freely.

  The base 1 and the height adjustment base 2 are firmly fixed with fixing bolts 7. The height adjustment of the lifting rod 3 can be realized by removing the fixing bolt 7 and selecting a set having an appropriate height from the plurality of height adjustment holes 8 opened in the base 1 and fixing it again. It is possible.

  The lifting bar 3 is connected to the frame support bar 4 via a spring pin 5, and a force in a direction in which the lifting bar 3 and the frame support bar 4 are always sandwiched acts.

  A lift bar anti-slip 6 is affixed to the surface of the lift bar 3 that contacts the wheelchair frame 15, and a base anti-slip 10 is affixed to the surface of the base 1 that contacts the floor.

  The base 1 is composed of a pair of left and right, and is firmly fixed by a base connecting plate 11 and has a structure without twisting or distortion.

  The height adjustment base 2 is composed of a pair of left and right, and is firmly fixed by the height adjustment base connection plate 9 and has a structure without twisting or distortion. The height adjusting base connecting plate 9 is a portion that serves as a power point of the lever, and a lifting handle 12 is provided in consideration of the operation with the hand of the assistant and the operation with the hand.

  Hereinafter, an embodiment of the operation of the above configuration will be described with reference to FIGS. Although there are no passengers in the figure, the operation is usually performed in the riding form.

  The stand of the present invention is inserted at an angle as shown in FIG. 3 from the rear side of the wheelchair with the driving wheel in the grounded state, and a pipe protruding at the rear part of the wheelchair frame between the lifting bar 3 and the frame support bar 4 (the name according to the Japanese Industrial Standard is “ Insert the tipping lever ”). The stand is autonomously held at this position by the effect of the spring pin 5.

  The operator (assistant) grasps the wheelchair handle 16 with both hands, puts one foot on the height adjustment base connection plate 9, then pulls the wheelchair handle 16 forward, and puts the foot on the height adjustment base connection plate 9. The wheelchair frame 15 is lifted according to the procedure of stepping on and the driving wheel (main wheel) is floated.

  Depending on various conditions such as the weight of the passenger and the arm strength of the assistant, the assistant can obtain the same effect by manually pushing down the lifting handle 12 provided on the height adjustment base connecting plate 9 without standing. Can do.

  At this time, due to the effects of the lifting rod anti-slip 6 and the base anti-slip 10, the present stand exhibits an effect with a stable operation.

  To return the wheelchair drive wheel to the grounded state, the operator (assistant) slowly pushes out the wheelchair handle 16 with both hands, or slowly lifts the lifting handle 12 provided on the height adjustment base connecting plate 9. .

  Details of the method for adjusting the height of the lifting bar 3 will be described with reference to FIGS. FIG. 6 shows a side surface of the base 1, and height adjustment holes 8a to 8f are provided as shown. FIG. 7 shows a side surface of the height adjusting table 2, and fixing holes 12a and 12b are provided as shown.

  The fixing hole 12 a of the height adjusting table 2 is fixed to either the height adjusting hole 8 a or 8 b of the base 1. The fixing hole 12b of the height adjusting base 2 is assigned to 8e or 8f in the case of a combination of 12a and 8a, and is assigned to 8c or 8d in the case of a combination of 12a and 8b to obtain lifting rods 3 having different heights. Is arranged to be.
